- Maximum Moisture % is not Defined – however as products are paid for on an Energy Basis
delivery of Very High Moisture Content material e.g. 65% + will attract a reduced rate. - Shredded Material containing long particles is not suitable for the plant as it can cause
blockages within the fuel handling systems
